Any machine that can forever without any extra energy given to it, is a perpetual motion machine obviously such machines requires energy to get than moving, but non thereafter. Every inventor, designer and scientist dreams of making such a machine which has the potential of solving most of the energy problems of this world. But the fact remains that it is impossible to develop such a machine.

Because at some point of their working they violate either the first or the second law of thermodynamics. Still many hopeful inventors over a period o ....etc

Introduction

What is MAC
-Controlling access to the channel
What is Z-MAC

- A Hybrid MAC which Combine the strengths of CSMA and TDMA while offsetting their weakness.

- The main feature of Z-MAC is its adaptability to the level of contention in the network .

CSMA (Carrier Sense Multiple Access)
It is pop ....etc

Abstract The pervasive adoption of IEE 802.11 radios in the past decade has made possible for the easy Internet access from a vehicle, notably drive-thru Internet. Originally designed for the static indoor applications, the throughput performance of IEE 802.11 in the outdoor vehicular environment is, however, still unclear especially when a large number of fast-moving users transmitting simultaneously. In this paper, we investigate the performance of IEE 802.11 DCF in the highly mobile vehicular networks. We first propose a simple yet accurate ....etc

ABSTRACT
Viruses: A virus is basically an executable file which is designed such
that first of all it should be able to infect documents, then it has to
have the ability to survive by replicating itself and then it should
also be able to avoid detection.
Computer viruses can be classified into several different types.
File or program viruses: They infect program files like files
with extensions like .EXE, .COM, .BIN, .DRV and .SYS. Some file viruses
just replicate whil ....etc

Spyware Overview
Spyware is a piece of software that gets installed on computer without your
consent.
It collects your personal information without you being aware of it.
Change how your computer or web browser is configured and bombard you with
online advertisements.
Spyware programs are notorious for being difficult to remove on your own and
slows down your PC.
A program gets installed in the background while you are doing something ....etc

Abstract

Contemporary network security applications generally require the ability to perform powerful pattern matching to protect against attacks such as viruses and spam. Traditional hardware solutions are intended for firewall routers. However, the solutions in the literature for firewalls are not scalable, and they do not address the difficulty of an antivirus with an ever-larger pattern set. The goal of this work is to provide a systematic virus detection hardware solution for network security for embedded systems. Instead of placing entir ....etc
